Under which conditions are the lac structural genes expressed most efficiently?
madam [21]

Lac genes are most effectively expressed in presence of Lactose and its analogs when glucose is absent.

Explanation:

A unit of prokaryotic gene expression and regulation,which includes structural genes and regulatory sequences recognized by regulatory gene product is called operon.

<em>Lac </em>structural genes are a part of<em> Lac</em> operon. The <em>Lac </em>operon consists of three, structural genes,an operator and a promoter.The product of Lac operon is involved in the conversion of disaccharide lactose into glucose and Galactose.

Lactose and its analogs are inducers of<em> Lac </em>operon. So, the structural genes are best expressed in presence of Lactose. Glucose and galactose are repressors of lac gene so the genes are repressed in presence of glucose.

The technique psychologists use to measure electrical activity in the brain is 1. EEG 2. Lesion 3. FMri 4. CAT Scan 5. PET Scan
posledela

Answer:

The correct answer is 1. EEG.

EEG or electroencephalography is a technique used to measure the electrical activity of the brain.

8 to 16 pairs of electrodes are placed on the scalp which record the electrical activity or impulses (in volts) generated by thousands of neurons or nerve cells present in the brain.

It provides the real-time imaging of the electrical activity of the brain.

The recorded impulses are first sent to the amplifier as the magnitude of the brain's electrical impulses is very low.

The amplifier then amplifies the results and show it on the screen in the form of voltage units.
